How can I make the objToRotate speed to rotate depending on the target moving speed?

Question

The player has these components: Animator, Rigidbody, Capsule Collider, Third Person Character (Script), Third Person User Control (Script), and the MyLookAT script.

The problem is if I drag the cube target too fast in the editor changing its position it will take some time for the objToRotate to rotate facing the target again. I want somehow to make that the objToRotate will know to set his own speed and to rotate fast/slow enough to face the target when moving the target.

I want the objToRotate to face the target in real-time when the target is moving not with delay.

using UnityEngine; using System; using System.Collections; public class RotatingTest : MonoBehaviour { public Transform target; public Transform objToRotate; public float speed = 1.0f; void LateUpdate() { Vector3 targetDirection = target.position - objToRotate.position; float singleStep = speed * Time.deltaTime; Vector3 newDirection = Vector3.RotateTowards(objToRotate.forward, targetDirection, singleStep, 0.0f); Debug.DrawRay(objToRotate.position, newDirection, Color.red); objToRotate.rotation = Quaternion.LookRotation(newDirection); } }

Do you still want a limited rotation speed at all? Or do you want to just delete the RotateTowards line and use LookRotation(targetDirection) instead? — DMGregory

@DMGregory If I delete the RotateTowrds line and using only the LookRotation like this objToRotate.rotation = Quaternion.LookRotation(target.position); it's not rotating at all. For now without limiting the speed just to rotate depending on the target speed movement. — Daniel Lip

Compare what you wrote in your comment to what I wrote in mine. I did not suggest passing target.position as the argument for Quaternion.LookRotation, because this function asks for a direction, not a position. — DMGregory

using UnityEngine; using System; using System.Collections; [RequireComponent(typeof(Animator))] public class MyLookAt : MonoBehaviour { public Transform target; public Transform objToRotate; void LateUpdate() { Vector3 relativePos = target.position - objToRotate.position; Quaternion rotation = Quaternion.LookRotation(relativePos, Vector3.up); objToRotate.rotation = rotation; } }
